The Biggest Snake in History of Reptiles

You’ve ever seen a big snake and thought: “wow, that’s a big snake!”, and then saw a bigger snake and even bigger one, yet, in a zoo, book or internet. Most of us have. And the question that comes up naturally, to many people, is “what is the biggest snake in history”? Well, I’m about to answer just that. If you’re Ophidiophobic – I’m sorry. Because this is The Biggest Snake in History of Reptiles article.


Titanoboa is the largest snake species of all time. Now, luckily for all you snake-fearing people out there, it’s extinct. It actually went extinct quite a long time ago. But it did exist and it was one hell of a reptile. So, let’s talk about it’s history, because it’s fascinating.


Well, first of all, we found out about this snake really recently. The evidence of it’s existence was discovered by a team of scientists working in the 10th world’s largest open-pit coal mine (bigger than Washington D.C. in area size) at Cerrejon in La Guajira, Colombia.

Scientists found fossils of Titanoboa in that mine that date back to about 58 to 60 million years ago. This snake lived in the Middle to Late Paleocene epoch, a 10-million-year period which followed the infamous Cretaceous-Paleogene extinction event, which happened 66 million years ago and led to the extinction of most of the life on Earth.

The species was identified as Titanoboa cerrejonensis, the largest snake ever found, which surpassed the previous largest found snake – Gigantophis.

Now, the big question – how big was it?

Look at how huge this snake was!


The fossils of the largest Titanoboa found suggest that is was 12.8 meters or 42 feet long, and weighed about 1,135 kilograms or 2500 pounds. Compare that to the largest snake living today – anaconda, who is, on average, 5.1 meters or 17 feet long and weighs about 250 kilograms or 550 pounds. It’s not even comparable.

Now, where did they live?


Titanoboas lived exclusively in area that the first fossils were found in – modern lowland tropics of northern Colombia, 100 kilometers or 60 miles from the Caribbean coast. That area is known to be the first recorded Neotropical forest in the world – 60 million years ago. It’s ecosystem didn’t just have the world’s largest snake living in it, but also one the world’s largest crocodiles – Purusaurus brasiliensis, and some other fascinating animals like Crocodylomorpha and certain very large turtles. Many of these animals were hunted by
